# pidstddata

Access coefficients of standard-form PID controller

## Syntax

## Description

`[`

returns the proportional gain
`Kp`

,`Ti`

,`Td`

,`N`

]
= pidstddata(`sys`

)`Kp`

, integral time `Ti`

, derivative time
`Td`

, and filter divisor `N`

of the
standard-form PID controller represented by the dynamic system
`sys`

.

If

`sys`

is a`pidstd`

controller object, then each output argument is the corresponding coefficient in`sys`

.If

`sys`

is not a`pidstd`

object, then each output argument is the corresponding coefficient of the standard-form PID controller that is equivalent to`sys`

.If

`sys`

is an array of dynamic systems, then each output argument is an array of the same dimensions as`sys`

.

`[`

also returns the sample time
`Kp`

,`Ti`

,`Td`

,`N`

,`Ts`

]
= pidstddata(`sys`

)`Ts`

. For discrete-time `sys`

that is not
a `pidstd`

object, `pidstddata`

calculates the
coefficient values using the default `ForwardEuler`

discrete
integrator formula for both `IFormula`

and
`DFormula`

. See the `pidstd`

reference page for more
information about discrete integrator formulas.
